No human being has ever seen a triceratops or velociraptor or even the mighty Tyrannosaurus rex. They left behind only their impressive bones. So how can scientists know what color dinosaurs were? Or if their flesh was scaly or feathered? Could that fierce T.rex have been born with spots?

In a first for young readers, the Sibert medalist Catherine Thimmesh introduces the incredible talents of the paleoartist, whose work reanimates gone-but-never-forgotten dinosaurs in giant full-color paintings that are as strikingly beautiful as they aim to be scientifically accurate, down to the smallest detail. Follow a paleoartist through the scientific process of ascertaining the appearance of various dinosaurs from millions of years ago to learn how science, art, and imagination combine to bring us face-to-face with the past.
